more sounds added to the previously posted music test. perhaps a final version. a video is still to be created, whenever time for it.
about the quality of the production:
all the music was created on my smartphone and tablet using different music and sound creation apps. there are countless options which i still haven't completely explored yet. this was just a test. as it was impossible to record the multiple sound sources directly on my android devices then i used an external dictaphone with line-in option, then used the recorded file to add more sounds on live playback. no mixing apps were used. due to several playbacks of the recordings with added layers of sound the sound quality has obviously deteriorated. i did my best i could with the cheap android devices and a very cheap dictaphone.
for a superior quality audio in my music creations i must get better recording devices. thus, the sound quality is not due to the lack of my hearing -- i am aware of all the issues with the final track, but that's the best i could produce right now.
similar issues will probably be with the video. i may need to resort to screen recording to produce the type of video i have imagined for the music. will see.
